German academics have now claimed the work impacts on the players’ performances and powers of recovery.
And Dr Ingo Frobose, of Cologne’s German Sports University, urged clubs to ban their players from having tattoos – insisting the ink is POISONING them.
Prof Frobose, 60, said: “I would forbid footballers from being tattooed. Clubs take every little aspect of their players’ health seriously, yet they don’t care about this behaviour at all.
“It would do clubs good if they paid more attention to their responsibilities, and the efficiency of their players.
“Various studies have shown that players suffer a three to five per cent drop in performance level after having a tattoo done.
“The skin is the largest organ that we possess – yet we poison it.

“Further research has shown that 60-70 per cent of the ink from tattoos doesn’t stay on the skin, but instead passes into the bloodstream.
“As a result one’s powers of recovery suffer, and you are no longer as fresh as previously. Green and blue lymph nodes can be a consequence.
“And large tattoos can affect the body’s ability to sweat and regulate its temperature.”
